A film examining the relationship between the late Rev Ian Paisley and Deputy First Minister Martin McGuinness is currently being filmed at Killylane Reservoir outside Larne.
The Journey stars English actor Timothy Spall as Ian Paisley and Irish star Colm Meaney as Martin McGuinness.
The film will tell the story of the relationship between the two men, who helped broker the power-sharing agreement between the DUP and Sinn Fein and became known as “The Chuckle Brothers.”
Harry Potter and Lord of the Rings star Sir John Hurt has also been lined up to play a veteran political fixer who oversees the St Andrews agreement.
In addition, Toby Stephens, who previously starred as a James Bond villain, will play former New Labour leader Tony Blair.
Charlie and The Chocolate Factory lead Freddy Highmore will also play a young civil servant who tries to improve the relationship between McGuinness and Paisley.
The director of the film is Belfast-born Nick Hamm, while Co Down author Colin Bateman has written the script.
Hamm, Mark Huffam (The Martian) and Piers Tempest (Like Minds) are producing the movie.
Stuart Ford’s IM Global is financing the project along with Northern Ireland Screen and will handle world sales.
Production is set to take place in parts of Northern Ireland and Scotland.
Spall is set to work on Alice In Wonderland sequel Alice Through The Looking Glass and earlier this year was nominated for an Oscar for his lead role in the film Mr Turner.
Colm Meaney has previously worked on Star Trek, and has guest-starred on Law and Order and The Simpsons.
